std::shared_ptr crash with MSVC on different computer?

Question

Compiling and running the following simple program works fine on my developer machine (Visual Studio 2015, 64-bit).

Running the same code on a different machine crashes with the windows error dialog, even though the x64-redistributables are installed (msvcp140.dll):

#include <memory>
#include <iostream>

int main(int argc, char **argv) {
  std::shared_ptr<int> test; // comment out to run on both machines

  std::cout << "Done: " << std::endl;
}

Removing the line with the shared pointer makes it work.

Any idea what the problem could be here, or how to debug?

Answer 1

I found the problem, in case this is useful for anyone:

In the windows event viewer, I discovered the reason for the crash: The exception was 0xc000001d or illegal instruction. Appareantly my code was compiled using the /arch:AVX compile flag, resulting in the following code for the snippet above:

int main(int argc, char **argv) {
00007FF749A816B0  sub         rsp,48h  
00007FF749A816B4  mov         qword ptr [rsp+20h],0FFFFFFFFFFFFFFFEh  
00007FF749A816BD  vpxor       xmm0,xmm0,xmm0  
00007FF749A816C1  vmovdqu     xmmword ptr [test],xmm0  
  std::shared_ptr<int> test; // comment out to run on both machines

  std::cout << "Done: " << std::endl;
00007FF749A816C7  lea         rdx,[string "Done: " (07FF749A86C70h)]  
00007FF749A816CE  mov         rcx,qword ptr [__imp_std::cout (07FF749A8A0D8h)]  
00007FF749A816D5  call        std::operator<<<std::char_traits<char> > (07FF749A8107Dh)  
  ...

As you can see, because of the /arch:AVX the vpxor and vmovdqu instructions were generated, which do not run on processors that are too old (like the one I tested with).

The solution is to have separate versions of the executable (or separate paths through the program) with and without AVX instructions to support older processors.
